For years, one of Bitcoin’s most widely accepted assumptions has been that Satoshi Nakamoto mined and still controls 1 million BTC. That estimate, which became deeply embedded in crypto discourse, largely traces back to a 2013 analysis by Sergio Lerner. By examining mining patterns in Bitcoin’s earliest blocks, Lerner argued that a dominant miner appeared to be active from the very beginning of the network and was likely responsible for an enormous stockpile of coins. Over time, that interpretation helped cement the view that Satoshi’s holdings amounted to just under 5% of Bitcoin’s total supply.
A later analysis by BitMEX Research, however, cast meaningful doubt on the certainty of that conclusion. Drawing heavily on Lerner’s original framework while reassessing the strength of the evidence, BitMEX Research argued that the case for assigning the full 1 million BTC to Satoshi may be weaker than many in the market had assumed. In its view, the evidence does support the idea that there was a dominant miner in 2009, but it does not necessarily justify the much more precise and widely repeated claim that this miner generated 1 million bitcoin.
Why the 1 Million BTC Figure Became So Influential
The 1 million BTC estimate has carried significance far beyond curiosity about Satoshi’s wealth. Because those coins have never been spent, many market participants have treated them as effectively removed from circulation, similar to coins believed to be permanently lost. This assumption influences discussions around Bitcoin’s real float, ownership concentration, and long-term supply dynamics. If Satoshi truly holds 1 million BTC and never intends to move them, that represents a substantial quantity of dormant supply sitting outside the active market.
That is why any revision to the estimate matters. BitMEX Research suggested that a more defensible range may be 600,000 to 700,000 BTC, implying that the traditional figure could be overstated by roughly 30%. While this still leaves Satoshi with one of the largest fortunes in Bitcoin history, it would materially alter how analysts think about the distribution of early-mined coins and the concentration of ownership in Bitcoin’s formative era.
BitMEX Research’s Core Argument
The central point from BitMEX Research was not that Satoshi held only a trivial number of coins. On the contrary, the report maintained that there is strong evidence pointing to a highly significant miner operating in Bitcoin’s earliest days. But the researchers emphasized that the evidence is less robust than many had come to believe. In other words, the existence of a dominant miner may be clear, while the exact identity of that miner — and the precise number of coins attributable to Satoshi — remains more uncertain.
That distinction is crucial. Over the years, the market often treated the 1 million BTC estimate as if it were a settled fact. BitMEX Research instead framed it as a probabilistic conclusion built on pattern analysis, one that can support a large estimate without necessarily validating the most famous number attached to Satoshi. Their preferred range of 600,000–700,000 BTC still points to an extraordinary stash, but one meaningfully smaller than the conventional narrative.
What a Lower Estimate Means Financially
A reduction from 1 million BTC to 700,000 BTC implies a difference of 300,000 BTC. At the valuation referenced in the original report, that would amount to roughly $2 billion wiped off the estimated size of Satoshi’s fortune. In absolute terms, that is an enormous sum. In practical terms, however, the immediate market significance is less dramatic if one accepts the broader assumption that these coins — whether 1 million or 700,000 — are unlikely to move.
The deeper impact is analytical rather than transactional. A lower estimate would revise how much of Bitcoin’s early supply should be thought of as tied to Satoshi specifically. It would also leave more room for the possibility that other early miners accumulated substantial coin balances during Bitcoin’s infancy, even if those balances have likewise remained untouched.
Supply, Distribution, and the Mystery of Dormant Coins
One reason the issue remains important is that Bitcoin’s circulating supply is not always discussed in purely mechanical terms. Analysts frequently distinguish between coins that exist on-chain and coins that are realistically available to the market. Satoshi’s holdings, because they have sat idle for so long, are often mentally categorized alongside lost coins. If BitMEX Research is right and some of the early block rewards commonly attributed to Satoshi were actually mined by someone else, then the interpretation of “Satoshi’s dormant supply” needs to be narrowed.
Still, the report also acknowledged a key point: even if some of those early coins belong to someone other than Satoshi, they may not be any more liquid in practice. The coins in question have remained static since they were issued as coinbase rewards in Bitcoin’s early years. Their inactivity means that, from the perspective of near-term market supply, the distinction may not change much unless those old wallets suddenly come alive.
The Larger Question: Will the Coins Ever Move?
Ultimately, the fascination around Satoshi’s wealth has always been tied to a bigger concern: what happens if those coins move? BitMEX Research ended by citing a statement from Satoshi Nakamoto: “You should never delete a wallet.” The quote is relevant because it supports the idea that if Satoshi is a single individual and is neither dead nor imprisoned, then the long dormancy of those coins may be a deliberate choice rather than an accident. That, in turn, reinforces the belief that the silence surrounding Satoshi’s stash is intentional.
As Bitcoin’s price has risen exponentially over the years, the decision not to spend or move such a vast holding has only become more striking. Whether Satoshi controls 1 million BTC, 700,000 BTC, or some number in between, the continued inactivity of those coins remains one of the most powerful signals in Bitcoin’s mythology. The market has grown accustomed to the assumption that they will stay frozen indefinitely, but that assumption has never been tested.
If those early coins were ever to move, the reaction could be severe. Traders would likely question whether Satoshi had returned, whether a long-dormant wallet had been compromised, or whether a previously untouchable source of supply was about to enter the market. Even if no selling followed, the symbolic effect alone could trigger broad uncertainty and panic. In that sense, the exact number of coins matters less than the latent power they represent.
An Enduring Bitcoin Mystery
The debate over Satoshi’s holdings illustrates a broader truth about Bitcoin history: some of its most foundational stories rest on careful inference rather than definitive proof. Lerner’s analysis gave the industry a compelling benchmark. BitMEX Research did not erase that benchmark, but it did argue for a more cautious reading of the available evidence. Instead of accepting 1 million BTC as settled fact, the newer interpretation encourages observers to view it as an influential estimate that may have overstated Satoshi’s actual share.
That leaves the community in a familiar position. Satoshi’s identity remains unknown. The true extent of the creator’s holdings remains uncertain. And the fate of those coins remains one of the biggest unanswered questions in the Bitcoin ecosystem. For now, whether the total is 1 million, 700,000, or somewhere in the middle, Satoshi’s dormant fortune continues to stand as one of the most enduring mysteries in cryptocurrency.
